26-4-2023 ANNA, VALENCIA - GREYLAG GOOSE (JUVENILE) (Anser anser)

https://www.inaturalist.org/taxa/7018-Anser-anser

Young greylags stay with their parents as a family group, migrating with them in a larger flock, and only dispersing when the adults drive them away from their newly established breeding territory the following year. At least in Europe, patterns of migration are well understood and follow traditional routes with known staging sites and wintering sites. The young learn these locations from their parents which normally stay together for life.
